The baby gains about 6 ounces this week as the body begins to fill out. This weight is in muscle, bone mass and the growing organs and tissues. The weight could top 1 1/3 pounds by the end of the week.

Between weeks 24 and 28, your care provider may order a glucose tolerance test to determine if you have gestational diabetes. Your uterus is 1 1/2 to 2 inches above the navel.

The structures of the spine - 33 rings, 150 joints and 1000 ligaments - begin to form. The blood vessels of the lungs are developing and the nostrils begin to open. Busy week!

You may be feeling like a "Soccer Mom" now that your uterus is the size of a soccer ball. Your growing uterus places pressure on your back and pelvis and may cause periodic shooting pains in your lower back and legs. When you experience this, rest, change your position, take a warm bath or apply ice to the sore area.

Sixth MonthYour baby could weigh about two pounds now and be around 9 inches long (crown of the head to the rump). As the blood vessels in the lungs began last week, the air sacs in the lungs begin this week. The lungs begin to secrete surfactant which covers the inner lining of the air sacs which then allows the lungs to expand normally during breathing.

Your uterus is about 2 1/2 inches above your belly button. If you feel your uterus suddenly tighten and then relax, don't panic. You're experiencing "Braxton Hicks" Contractions. These are normal, usually painless or feel similar to menstrual cramps and happen at irregular intervals. They are your body's way of practicing for the real thing and help to tone up your uterus for the tough job of labor.

During this week, the brain continues its rapid growth, and the lungs continue to grow. Eyelids begin to open, and the retinas begin to form. The baby will grow over 1/2 inch this week and will be about 1 1/3 feet long (from crown of head to the toes or 9.6 inches from crown to rump)!

Congratulations! At the end of this week, you will have finished the second trimester already! You may be experiencing some shortness of breath. Your uterus is close to your rib cage now, and your lungs may not be able to fully expand. Don't worry though. Your baby isn't lacking oxygen and your circulatory system is actually working more efficiently thanks to those pregnancy hormones that have caused you so much discomfort.

Our little miracle is growing and developing at an astonishing rate! Eyebrows and eyelashes are now present, and the hair on the head is growing. The eyelids open, and the eyes are completely formed. The body is getting plumper and rounder (weighs about 2 pounds) and is composed of around 2 to 3% body fat. Muscle tone is gradually improving. The lungs are capable of breathing air but if the baby is born now, it would struggle to properly breathe. Be sure to talk to your baby a lot because s/he can recognize your voice now!

Welcome to the third trimester ~ the period of leg cramps, hemorrhoids, varicose veins, itchy skin, aches and pains, swelling, heartburn, indigestion and . . . your baby's arrival!

The baby's head is in proportion to the rest of the body. Fat continues to accumulate under the skin. The brain can control primitive breathing and body temperature control, and the eyes can move in the sockets. The baby is becoming sensitive to light, sound, taste and smell. Now, I wonder how experts know a baby can smell in utero?

Do you feel like you've been pregnant forever? Are those discomforts of pregnancy getting to you? This is the time when itchy skin, shortness of breath, hemorrhoids, leg cramps, heartburn and indigestion and achy muscles takes a toll. What do you do? Remember that these annoyances are temporary. Focus on the positive aspects of pregnancy!

Our little one is nearly three pounds already and growing like a weed. The early lanugo is disappearing, the eyelids open and close, and the toenails are growing. The bone marrow is now responsible for red blood cell production.

The best sleeping position for a pregnant woman is on her left side. Your aorta and vena cava are slightly to the right of the center of your back, so laying/sleeping on your left side as much as possible ensures an unobstructed blood flow to your organs and extremities. You may be having some trouble sleeping now. Try one of the many maternity pillows or full-body pillows on the market. Sleeping in a recliner chair might also help, especially when the heartburn gets nasty.

Growth begins to slow a teeny bit, and the brain goes through a period of rapid development. The only major organ left to fully develop is the lungs. If your baby is a boy, his testes begin to descend from the body cavity to the scrotum

Your abdomen may be aching frequently now as your uterus is stretching more and more. Your uterus is about 4 1/2 inches above your belly button with ten weeks to go. As your baby's bones harden and grow, your calcium needs are even greater. Be sure your diet is adequate in calcium, protein, iron and folic acid

The baby is up to four pounds now and all five senses are functional. The toenails are completely formed and the hair on the head continues to grow.

You'll be gaining about a pound a week. Mild edema is normal but if you experience severe headache; seeing "spots" or "flashing lights" while at rest; sudden increase in swelling, such as over 2-3 days, especially of the face; abdominal pain; and nausea, vomiting, and feeling sick, contact your caregiver immediately. You could be developing pre-eclampsia which is characterized by swelling, high blood pressure and protein in the urine. It is a very serious complication of pregnancy.

At this point, the amniotic fluid is at the highest level in the pregnancy. The amount will remain constant until delivery. Rapid brain growth has increased the baby's head size approximately 3/8 of an inch this week. Fat continues to accumulate which turns the baby's skin color from red to pink.

Over halfway there, and you're probably showing now. Your uterus is about 1/2 inch above your belly button. The average weight gain is between 10 and 15 pounds at this point. If you're eating a healthy diet, don't count pounds and calories too strictly. Emotionally, you're probably feeling more stable and comfortable.

The baby responds as a newborn with its eyes open while awake and closed while sleeping. S/he is developing immunities to fight mild infection. Those sharp little fingernails are at the ends of the fingertips already, and you might need to clip them during the first few days after birth.

Changes in Mom

You've probably felt some Braxton Hicks contractions for the past several weeks but they may intensify now. They are usually painless and non-rhythmical. These are preparing your body for the real thing.
